摘要 这篇文章提供了一个关于递归神经网络中某些概念的指南.与前馈网络不同,RNN可能非常敏感,并且适合于过去的输入(be adapted to past inputs).反向传播学习(backpropagation learning)是为了前馈网络而描述,并进行调整来满足我们的建模需要,并且推广到递归网络.这篇简要的文章的目的是搭建一个应用和理解递归神经元网络的图景(scene). 1.简介 广为人知的是,给定了一个隐藏节点的集合(可能非常大),传统的前馈网络可以用来近似任何空间受限的有限函数.…

When a golf player is first learning to play golf, they usually spend most of their time developing a basic swing. Only gradually do they develop other shots, learning to chip, draw and fade the ball, building on and modifying their basic swing. In a…

(一)Highway Networks 与 Deep Networks 的关系 理论实践表明神经网络的深度是至关重要的,深层神经网络在很多方面都已经取得了很好的效果,例如,在1000-class ImageNet数据集上的图像分类任务通过利用深层神经网络把准确率从84%提高到了95%,然而,在训练深层神经网络的时候却是非常困难的,神经网络的层数越多,存在的问题也就越多(例如大家熟知的梯度消失.梯度爆炸问题,下文会详细讲解).训练起来也就是愈加困难,这是一个公认的难题. 2015年由Rupesh…

Training Neural Networks: Q&A with Ian Goodfellow, Google Neural networks require considerable time and computational firepower to train. Previously, researchers believed that neural networks were costly to train because gradient descent slows down n…

About this Course This course will teach you how to build convolutional neural networks and apply it to image data. Thanks to deep learning, computer vision is working far better than just two years ago, and this is enabling numerous exciting applica…

About this Course This course will teach you the "magic" of getting deep learning to work well. Rather than the deep learning process being a black box, you will understand what drives performance, and be able to more systematically get good res…
